One Person Always Lies, Another always Tells Truth

You have to go to a place and there are two paths. You don't know which path leads to your destination. There are two watchmen at the entrance. One person always tells truth, and another one always tells lies. You can ask only one question to one person. What question would you ask to find the way to your destination?

If I ask the other person, the way to the destination, what would he tell?

Whatever he says, that is not the correct path. Take the other path.
